Embodiment
The utility model is described in further detail with reference to embodiment, but embodiment of the present utility model is not
It is limited to this.
Embodiment 1：
With reference to shown in accompanying drawing 1-5, a kind of indoor automatic sunshade system based on ultrasonic measurement, including controller, with control
Illuminance sensor U1, the temperature sensor U2 of device connection processed and the keyboard input module for inputting given threshold, in addition to
The motor drive block and ultrasonic wave transmitting and receiving module being connected with controller, the motor drive block includes positive and negative
Turn motor, rotating motor also drive connection has slide unit, and the slide unit also slidably connects rectangular rail, institute
The hook for stating slide unit and curtain is detachably connected, and ultrasonic wave transmitting and receiving module is installed with the slide unit,
Glide direction of the rectangular rail along slide unit offers rectangular opening, and the rectangular opening is used to provide cunning to the hook of curtain
Dynamic rail road, one end of the rectangular rail are provided with the baffle plate for reflectance ultrasound ripple.
Operation principle and application method：
The illuminance sensor U1 and temperature sensor U2 be arranged between curtain and window, for detect illuminance and
Temperature.Keyboard input module is used to set automatic control mode and manual mode and sets the scope and temperature value of illuminance,
Can be according to different time sections such as daytime and evening, Various Seasonal such as spring, summer, autumn and winter to illumination and the demand of temperature, setting difference
Illuminance scope and temperature value, be stored in the internal processes of controller.When width such as window is W, setting：
At night, no matter illuminance and temperature, are set as full-shut position；
On daytime, during illuminance ＜ 100lx, curtain is shown in a fully open operation；
During 100lx≤illuminance≤200, curtain opens 3/4W；
During 200lx ＜ illuminance≤300, curtain opens 1/2W；
When illuminance is more than 300lx, curtain opens 1/4W；
When illuminance is more than 300lx and temperature and is higher than 25 degree, curtain is closed.
When illuminance sensor U1 and temperature sensor U2 by the information transfer of collection to controller when, controller is according to setting
Fixed illuminance scope and temperature value carry out analysis judgement, judge that now curtain should standard-sized sheet, fully closed or regulation curtain opening
Size, it is necessary to when taking action, the transmitter transmitting ultrasonic wave of controller control ultrasonic wave transmitting and receiving module, and by interior
The time T1 of portion's timer record now, ultrasonic wave run into the baffle plate of rectangular rail one end in communication process, form reflection, instead
The ultrasonic wave penetrated receives ultrasonic wave by the receiver of ultrasonic wave transmitting and receiving module, and input controller, controller record this
When time T2, it is ultrasonic wave thus to calculate now slide unit the distance S=V* (T2-T1)/2 apart from baffle plate, wherein V
Spread speed, so as to judge that slide unit should still open the direction slip of curtain to closing curtain.If now slide
The distance of member distance baffle plate is 1/2W, judges that now curtain should open 1/4W according to current illuminance and temperature, i.e., sliding
Dynamic component should slide 1/4W to the position for closing curtain, and two inputs that now controller is connected with motor drive block are defeated
Exit port exports, one of output high level, another output low level, to drive rotating motor rotation, rotating
Motor driving slide unit slides, and during slide unit slides, ultrasonic wave transmitting and receiving module still detects slip
The position of part, when the distance between slide unit sliding position and baffle plate are 1/4W, controller and motor drive block
Two input/output ports of connection export low level, stop driving rotating motor, and slide unit stops sliding.
When illuminance and temperature change, and the size that curtain needs standard-sized sheet, fully closed or curtain to open needs regulation,
Repeat the above steps and be adjusted, be no longer described in detail again.For setting automatic control mode and manual mode and setting illumination
The scope of degree and the keyboard input module of temperature value select matrix keyboard circuit commonly used in the prior art, will not be described in detail herein.
